Kester 24-6337-0010 44 Rosin Core Solder 63/37 .020 1 lb. Spool

I thought solder should be a simple product that works, but you get what you pay for. Cheap Chinese solder will waste your time/effort/parts/PCB/etc. etc. Get this solder and keep working.

Perfect

Good size for fine through-hole work. Flux gives perfect wetting and doesnt smell terrible.

top notch

Best solder on the market at this price point. Perfect for amateurs and pros alike! Price is right and of course, since it’s Amazon, the shipping time is too.

Solders amazingly, fills, wicks, and has almost no plastic state

Very good solder. Much better than thicker solders sold with soldering irons!

I am used to Alphametals made in Brazil. The trade mark is BEST and it is really the best. This one from Kester is not good at all. The flux core is not continuous, so when you stat soldering, some spots go fine and some dont. I need to use extra SMD flux paste to finish the job, what takes longer and compromises the quality. I would say do not buy, but these company took over the market and that is the only option we have. The other option is to import from BEST in Brazil.

that item is good !

Its Kester 44. The gold standard. What more needs to be said?
